COUNTER.

Patented Nov. 19, 1912.

Application filed November 10, 1810. SeriaLNo. 591,737.

Be it known that I, CURTIS Hussnr V EE- DER, a citizen of the UnitedStates, residing in the city ofHartfo-rd, in the State of Connecticut,have invented certain new and useful Improvements in Counters, of whichthe following is a specification, reference being had to theaccompanying drawings, forming a part hereof.

This invention relates to registers I or counters in which the severalindex or number wheels or rings are mounted upon a common axis and areactuated. one from another, through suitable transmitting mechabeingactuated from some external source.

One objectof the invention is to improve the construction, with a viewto a reduction in the cost of manufacture, this feature of improvementbeing generally applicable to counters of the class referred to, andanother object of the invention is to improve of the lowestdenomination, this feature of the invention being especially applicableto counters which are actuated directly from a rotary or rotaryoscillating shaft.

The invention will be more fully exdrawings in which it is illustratedand in which- Figure l is a top view, partly broken out, of a counterwhich embodies the present improvements, the actuating shaft being alsoshown. Fig. 2 is a view in longitudinal section on the plane indicatedby. the line 2-2 of Fig. 1, but on a larger scale. Fig, 3 a view inelevation as seen from the righthand in Fig. 2. Fig. 4 is a view insection on the plane indicated by the line. 4-4 of Fig. 2, looking inthedirection of-the arrows. l

.The couhting mechanism comprises incentral shaft a, which is also, inthe construction shown, the driving shaft for thewheel of the lowestdenomination, end plates 7) and b in which the shaft a is mounted, indexor number wheels or rings 0, c, &c., which are mounted on the shaft a,transmitting mechanism d, d, &c., between successive index rings, shellsor frames e, e, &c., each of which carries the correspondingtransmitting mechanism (l, d. &c., and receives thecorresponding indexrings 0. c,'

series, the several sectional units, eachof which, being made up of theparts enumerated, is complete in itself and, as to all except the endunits,=is identical with every other. I In the construction shown in thedrawings, particularly in Figs. '1 and 2, the means provided for thepurpose of securing the sectional units together consist of an outsideshell f into which the several units are forced, but obviously otherequivalent means may beemployed for the purpose.

The invention is not concerned with the .Darticular construction of theindex rings and the transmitting mechanism and as any usual or suitableform and arrangement of such devices may be employed no attempt is madeherein to illustrate or to describe such devices in detail. i diate unitis identical with every other it is possible to make up at any time acounter with any desired number of index or number rings or wheels,without requiring any great stock of parts to be carried or differenttools for the production of different parts to be provided. The outsideshell may be made from ordinary tubing, out off at any desired nationfro m the center shaft (1. As shown,

the shaft is provided with a transverse pin a which is adapted to engagethe internal gear teeth 0" of the first index ring. The drivingmechanism, through whic movement is imparted to the center's t 0;. asshown in the drawings, has been devised with special reference to use ofthe counter in connection with a pump which may have a variable throw,the special pur ose in view being to prevent the operation of the pumpby short strokes without cc'untihg. As shown, a rotary oscillatingshaftz', connected with the pump mechanism, is provided with an arm 2"which engages a plate 70 notched, as at k", and mounted on a stud Zwhich is secured in the frame or casing m. On the inner face of theplate is are mounted spring-pressed pawls n, n on opposite sides of theaxis. These pawls engage a fine toothed ratchet wheel 0 which is alsomounted on the stud Z. Spring-pressed hold pawls Since each intermc- 1),2 also engaging the teeth of the ratchet wheel 0, are mounted on a. ringr which eneirelesthe ratchet wheel 0 and is supported by lugs m, m onthe frame or casing at, being secured thereto by screws of. 'The ratchetwheel 0 has secured thereto or formed therewith a pinion 0 which mesheswith a gear 0 fast on the center shaft a. It will be observed byinspection of Fig. 4, not only that the teeth on the rah het wheel 0 aretine but that the opposite pawls are offset with respect todiametrically opposite teeth of the ratchet wheel. So that when the pawlat one side is at the bottom of the ratchet tooth the pawl at the otherside is half way up the corresponding ratchet tooth, whereby the pawlcarrying plate la is moved through onl one half of the angular space ofa ratchet tooth to secure a fresh hold and a very slight moven'ient ofthe actuating shaft 1' is therefore sntlicient to produce a Forwardmovement of the counting mechanism.

It will be understood that the 'fOllllO'f the parts may be varied tosuit diti'erent conditions of use and that the invention is notrestricted to the precise details of construction shown and describedherein.

I claim as my invention:

1. In a counter, the combination with an index ring and a supportingframe or casing, of driving mechanism comprising a ratchet wheel.transmitting devices between the ratchet wheel'and the index ring, and apawl carrying plate mounted on the same axis with the ratchet wheel andhavingbpposite pawls engaging the teeth of the ratchet wheel.

2. In a counter, the combination with an index ring and a supportingframe or casing, of driving mechanism comprising a ratchet wheel,transmitting devices between the ratchet wheel and the index ring, and apawl carrying plate mounted on the same axis with the ratchet wheel andhaving opposite pawls engaging the teeth of the ratchet wheel, theopposite pawls being ofi'set with respect to diametrically oppositeteeth on the ratchet wheel so that the pawl at one side is at the bottomof the corresponding ratchet tooth while the pawl on the opposite sideis half way up the corresponding toot-h.

3. In a counter, the combination with an index ring and a supportingframe or casing, of driving mechanlsm comprising a ratchet wheel,transmitting devices between the ratchet wheel and the index ring, apawl carrying plate mounted on the same axis with the ratchet wheel andhaving opposite pawls engaging the teeth of the ratchet wheel, a ringsecured on the frame or casing and encircling the ratchet wheel and holdpawls carried by said ring and engaging the ratchet wheel.
